Description
[0001] Digital printing techniques will become increasingly
important in the future in the textile area as well as in the
nontextile area.
[0002] Changed market expectations in conventional textile printing
demand more flexibility in design, color and delivery time. Digital
inkjet technology is the answer. By making it possible to print
directly from the computer via printing nozzles onto textiles
without the need to prepare printing screens, this new technology
improves printing process flexibility, efficiency and environmental
performance. It provides substantially integrated operations,
shortens printing times and meets the demand for rapid reaction to
market developments and for fewer intermediate stages in the
manufacturing operation.
[0003] The inkjet printing process is usually carried out using
aqueous inks, which are sprayed as small droplets directly onto the
substrate. There is a continuous form of the process, in which the
ink is pressed piezoelectrically through a nozzle at a uniform rate
and deflected onto the substrate by an electric field, depending on
the pattern to be produced, and there is an uninterrupted inkjet or
drop-on-demand process, in which the ink is expelled only where a
colored dot is to appear. The latter form of the process employs
either a piezoelectric crystal or a heated cannula (bubble or
thermal jet process) to exert pressure on the ink system and so
eject an ink droplet. These techniques are described in Text. Chem.
Color, volume 19 (8), pages 23 ff and volume 21, pages 27 ff.
[0004] This highly sensitive microtechnology requires the
development of tailored dye preparations (inks) meeting, for
example, high requirements with regard to purity, particle size,
viscosity, surface tension, conductivity, physico-chemical
stability, thermophysical properties, the pH, the absence of foam,
color strength, fastness level and stability in storage.
Commercially available reactive dyes in the form of their powder,
granular or liquid formulations of the kind used for conventional,
analog textile printing contain significant electrolyte quantities,
dustproofing and standardizers which lead to massive problems in
inkjet printing. On the other hand, dye inks as used for nontextile
materials, for example paper, wood, plastics, ceramics, etc.
provide only unsatisfactory results with regard to ease of
application and print color yield and fastnesses on textile
material. All prior art textile inks rely on chromophores from
conventional textile printing which permit the production of
relatively bright hues, but do not have fluorescent properties.
Fluorescence is needed for special fashion effects as well as for
safety clothing.
[0005] It is an object of the present invention to provide printing
inks which do not have the abovementioned disadvantages.
[0006] It has now been found that, surprisingly, inks based on
reactive xanthene dyes as known from DE 2 132 963 give excellent
results.
[0007] The present invention accordingly provides novel aqueous
textile inkjet printing inks including a reactive fluorescent
xanthene dye of the general formula (1) ##STR2## where [0008]
R.sup.1 and R.sup.2 are independently hydrogen atom, halogen atoms,
preferably chlorine or bromine atoms, (C.sub.1-C.sub.4)-alkyl- or
(C.sub.1-C.sub.4)-alkoxy-, [0009] X is an oxygen or sulfur atom or
a CO group, [0010] m is a number from 1-3, and [0011] R.sup.3 is a
radical of the general formula (2) ##STR3## [0012] where [0013] W
is a bivalent bridge member, such as for example a C.sub.1 to
C.sub.4-alkylene, [0014] A is a bivalent mono- or dinuclear
aromatic radical, for example a phenylene or naphthylene group or a
bivalent diphenyl, diphenyl ether, diphenylamine, diphenyl sulfide
or diphenyl sulfone radical and may be substituted in the aromatic
nuclei by halogen atoms, preferably chlorine or bromine atoms,
lower alkyl groups, lower alkoxy groups, hydroxyl, carboxyl, sulfur
or nitro groups, [0015] B is a bivalent bridge member such as for
example a C.sub.1 to C.sub.4-alkylene or --NR.sup.41--, wherein
R.sup.41 is a hydrogen atom or a lower optionally substituted alkyl
radical, such as preferably a methyl, ethyl, .beta.-hydroxyethyl or
.beta.-sulfatoethyl group, [0016] Y is a reactor group [0017] n, p,
q are 0 or 1, and [0018] r is 1 or 2.
[0019] Reactor groups Y are groups which comprise one or more
reactive groups or detachable substituents that, on application of
the dyes to cellulosic materials in the presence of acid-binding
agents with or without heating, are capable of forming covalent
bonds with the hydroxyl groups of the cellulose or, on application
to superpolyamide fibers, such as wool, are capable of forming
covalent bonds with the NH groups of these fibers.
[0020] Reactor groups suitable for the purposes of the present
invention which contain at least one detachable substituent bound
to a heterocyclic radical or to an aliphatic radical include those
which contain at least one reactive substituent bound to a 5- or
6-membered heterocyclic optionally substituted ring, such as a
monazine, diazine, triazine, for example pyridin, pyrimidine,
pyridazine, pyrazine, thiazine, oxazine or asymmetrical or
symmetrical triazine ring, or to such a ring system which comprises
one or more fused-on aromatic rings, such as a quinoline,
phthalazine, cinnoline, quinazoline, quinoxaline, acridine,
phenazine and phenanthridine ring system; the 5- or 6-membered
heterocyclic rings which comprise at least one reactive substituent
are accordingly preferably those which contain one or more nitrogen
atoms and may contain fused-on 5- or preferably 6-membered
carbocyclic rings. Examples to be mentioned of reactive
substituents on the heterocycle are halogen, such as fluorine,
chlorine or bromine, ammonium including hydrazinium, sulfonium,
sulfonyl, azido, thiocyanato, thio, thioether, oxyether, sulfinic
acid and sulfonic acid. Specific examples to be mentioned are

[0035] For the inks to be used in the continuous flow process, a

[0049] The printing inks of the invention may further include
customary additives, for example viscosity moderators to set
viscosities in the range from 1.5 to 40.0 mPa*s in a temperature
range from 20 to 50.degree. C. Preferred inks have a viscosity of
1.5 to 20 mPa*s and particularly preferred inks have a viscosity of
1.5 to 15 mPa*s.
[0050] Useful viscosity moderators include rheological additives,
for example:
polyvinylcaprolactam, polyvinylpyrrolidone and their copolymers
polyetherpolyol, associative thickeners, polyurea, polyurethane,
sodium alginates, modified galactomannans, polyetherurea,
polyurethane, nonionic cellulose ethers.
[0051] As further additives the inks of the invention may include
surface-active substances to set surface tensions of 20 to 65 mN/m,
which are adapted if necessary as a function of the process used
(thermal or piezotechnology).
[0052] Useful surface-active substances include for example:
nonionic surfactants, butyldiglycol, 1,2-hexanediol.
[0053] The inks may further include customary additives, for
example substances to inhibit fungal and bacterial growth in
amounts of 0.01 to 1% by weight based on the total weight of the
ink.
[0054] The inks may be prepared in a conventional manner by mixing
the components in water.
[0055] The dye inks of the invention are useful in inkjet printing
processes for printing a wide variety of pretreated materials, such
as silk, leather, wool, polyamide fibers and polyurethanes, and
especially cellulosic fiber materials of any kind. Such fiber
materials are for example the natural fiber cellulose fibers, such
as cotton, linen and hemp, and also pulp and regenerated cellulose.
The printing inks of the invention are also useful for printing
pretreated hydroxyl- or amino-containing fibers present in blend
fabrics, for example blends of cotton, silk, wool with polyester
fibers or polyamide fibers.
[0056] In contrast to conventional textile printing, where the
printing ink already contains all the fixing chemicals and
thickeners for a reactive dye, in inkjet printing the auxiliaries
have to be applied to the textile substrate in a separate
pretreatment step.
[0057] The pretreatment of the textile substrate, for example
cellulose and regenerated cellulose fibers and also silk and wool,
is effected with an aqueous alkaline liquor prior to printing. To
fix reactive dyes there is a need for alkali, for example sodium
carbonate, sodium bicarbonate, sodium acetate, trisodium phosphate,
sodium silicate, sodium hydroxide, alkali donors such as, for
example, sodium chloroacetate, sodium formate, hydrotropic
substances such as, for example, urea, reduction inhibitors, for
example sodium nitrobenzenesulfonates, and also thickeners to
prevent flowing of the motives when the printing ink is applied,
for example sodium alginates, modified polyacrylates or highly
etherified galactomannans.
[0058] These pretreatment reagents are uniformly applied to the
textile substrate in a defined amount using suitable applicators,
for example using a 2- or 3-roll pad, contactless spraying
technologies, by means of foam application or using appropriately
adapted inkjet technologies, and subsequently dried.
[0059] After printing, the textile fiber material is dried at 120
to 150.degree. C. and subsequently fixed.
[0060] The fixing of the inkjet prints prepared with reactive dyes
may be effected at room temperature or with saturated steam, with
superheated steam, with hot air, with microwaves, with infrared
radiation, with laser or electron beams or with other suitable
energy transfer techniques.
[0061] A distinction is made between one- and two-phase fixing
processes:
[0062] In one-phase fixing, the necessary fixing chemicals are
already on the textile substrate.
[0063] In two-phase fixing, this pretreatment is unnecessary.
Fixing only requires alkali, which, following inkjet printing, is
applied prior to the fixing process, without intermediate drying.
There is no need for further additives such as urea or
thickener.
[0064] Fixing is followed by the print aftertreatment, which is the
prerequisite for good fastnesses, high brilliance and an impeccable
white ground.
[0065] The prints prepared with the dye inks of the invention,
especially on cellulose fiber materials, have high color strength
and a high fiber-dye bond stability not only in the acidic but also
in the alkaline range, good lightfastness and very good wetfastness
properties, such as wash, water, seawater, cross-dyeing and
perspiration fastnesses, and also good fastness to heat setting and
pleating and crockfastness.
[0066] The examples which follow illustrate the invention. Parts
and percentages are by weight, unless otherwise stated. Parts by
weight relate to parts by volume as the kilogram relates to the
liter.
